1. The venue we use for our London conference has a conservatory with a glass roof. While we had lunch there, we saw a crane on a nearby building site moving a skip high overhead. My father always says that while there are cranes in the city, everything's all right.
2. The biscuits at the conference venue, and seeing one of our speakers pocketing a few packs. He said he'd come back because he'd forgotten his coat.
3. The O. Henry story, The Head-Hunter.
